find $r$ as a function of $R$; where $R$ is the distance between the bubble and the center of Earth. [The radius of Earth is $R_e$]
Assume we have a long column of water and an air bubble of radius $r$ and pressure $P_0$ at the surface of the Earth is rising inside that. If the column is long enough for $g$ not to be considered constant,
